One of the serious diseases of potato which can cause even total loss.

1. This disease damages leaves, stems and tubers.

2. Affected leaves appear blistered as if scalded by hot water and eventually rot and dry out.

3. When drying out, leaves turn brown or black in color.

4. When infections are still active, spots appear on the underside of leaves blanketed in what looks like flour.

5. Affected stems begin to blacken from their tips, and eventually dry out.

6. Severe infections cause all foliage to rot, dry out and fall to the ground, stems to dry out and plants to die.

8. This disease acts very quickly. If it is not controlled, infected plants will die within two or three days.
